I once tested the old fan as you just described and it worked very well. It blew on full blast. Right now I just purchased a brand new fan (as the old one was broken in the accident) so I know that the fan not working will be out of the question - for the most part, save for perhaps a manufacturing defect. So what do you suggest I do? Start by replacing the temperature and pressure switches on the receiver/drier?
